The laser diode in the optical pick-up block may suffer electro-
static break-down because of the potential difference generated by 
the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also 
use the procedure in the printed matter which is included in the 
repair parts.
The fl exible board is easily damaged and should be handled with 
care.

NOTES  ON  LASER  DIODE  EMISSION  CHECK
The laser beam on this model is concentrated so as to be focused 
on the disc refl ective surface by the objective lens in the optical 
pickup block. Therefore, when checking the laser diode emission, 
observe from more than 30 cm away from the objective lens.

UNLEADED  SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution:  Some printed circuit boards may not come printed with 

the lead free mark due to their particular size)

Unleaded solder has the following characteristics.
•  Unleaded solder melts at a temperature about 40 °C higher 

than ordinary solder.

 

Ordinary soldering irons can be used but the iron tip has to be 
applied to the solder joint for a slightly longer time.

 

Soldering irons using a temperature regulator should be set to 
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if 

the heated tip is applied for too long, so be careful!

• Strong 

viscosity

 

Unleaded solder is more viscous (sticky, less prone to fl ow) 
than ordinary solder so use caution not to let solder bridges 
occur such as on IC pins, etc.

• 

Usable with ordinary solder

 

It is best to use only unleaded solder but unleaded solder may 
also be added to ordinary solder.

1. BLX-104
Procedure:
1. Select 

23.976Hz/1080p.

2.  Play “4.Motion picture”.
3.  Check whether player can play back or not.
4.  Check each outputs.
 Video:
 Composite/HDMI.
 Audio:
 Speaker 

out.

*  When 1080/24p monitor is nothing, 1080i (59.94Hz or 50Hz) 

can use instead of 1080/24p.

 

However this is temporary correspondence.

*  When the output of HDMI is 1080p/1080i/720p, the signal of 

composite is not output.

 

It is necessary to lower the output of HDMI to 480p or 576p or 
less.

2. BLX-204
Procedure:
1.  Select 1080i (59.94Hz or 50Hz).
2.  Play “4.Motion picture”.
3.  Check whether player can play back or not (Check the picture 

and sound output).

3. CD (HLX-A1)
Procedure:
Check whether player can play back or not (Check the sound out-
put).

4.  HLX-513/514 (NTSC), HLX-506/507 (PAL)
Procedure:
1.  After displayed Main Menu, select “1.Video Signal”.
2.  Play “1.Color bar 100%” (Check the picture and sound out-

put).

3.  Return to Menu.
4.  Play “Demonstration 4:3” or “Demonstration 16:9” (Check the 

picture and sound output).

NOTE  OF  REPLACING  THE  IC101  AND  IC501  ON  
THE  MB-149  BOARD
IC101 and IC501 on the MB-149 board cannot exchange with 
single. When these parts are damaged, exchange the complete 
mounted board.

NOTE  OF  REPLACING  THE  IC102,  IC103,  IC202  AND  
IC203  ON  THE  MB-149  BOARD
Replacement of IC102, IC103, IC202 and IC203 on the MB-149 
board used in this unit requires a special tool.

NOTE  OF  REPLACING  THE  TOUCH  BOARD
When the TOUCH board is defective, exchange the complete 
mounted board.

RELEASING  THE  DISC  SLOT  LOCK
The disc slot lock function for the antitheft of an demonstration 
disc in the store is equipped.

Releasing Procedure:
1.  Press the [

?/1

] button to turn on the system.

2.  Press the [HOME] button on the remote commander to enter 

the home menu.

3.  Touch the [

x

] and [

Z

] sensors simultaneously and hold down 

unit “DEMO OFF” displayed on the fluorescent indicator tube 
(around 5 seconds).

Note: When “DEMO.LOCK” is displayed, the disc slot lock is not re-

leased by turning power on/off with the [?/1] button.

ABOUT  THE  LENS  CLEANING
Do not do the lens cleaning with the cotton bud etc. It causes the 
trouble.
